IMPROVEMENT IN GRAIN ELEVATORS AND MEASURES.

Specification forming part of Letters Patent No. 1 84,616, dated November 21, 1876; application filed March 18, 1876.

To all whom it may concern:

Be it known that I, JAMES M. HARPER, of El Paso, in the county of Woodford and State of Illinois, have invented a new andvaluable Improvement in Grain Elevators and Measnrers and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked there- Figure 1 of the drawings is a representation of a side elevation of my grain elevators and ineasurers, part sectional; and Fig. 2 is a vertical section of the same.

This invention has relation to means for elevating grain from a thrashing-machine and measuring it; and the nature of my invention consists in the novel construction and arrangement of the parts, as will he hereinafter explained.

In the annexed drawings. A represents a trunk, which is vertically divided, and provided near its lower end with a hopper, and an opening, a, near its lower end. Inside of this trunk is an endless belt, I), which passes around'two pulleys, 0 c and has attached to it, at suitable distances apart, cups or buckets'd. The shaft of the upper pulley c has a, drum, c keyed on it, around which a belt clined trunk, B. O 0 are two cut-off valves, which are free to slide 'in kerfs made in the trunk B, and which are arranged at such a distance from each other that they will measure the grain by half-bushels. These cut-off valves 0 O are loosely attached to a vibrating lever, D, fixed to a rock-shaft, E, which is applied in bearings on the outside of the trunk B. One end of the shaft E has an arm, 7, secured to it, to the free end of which a pawl, g, is pivoted, which engages with ratchetteeth on a wheel, G. At every discharge of grain from the trunk B the pawl moves the wheel G the distance of one tooth, registering halfbushels, and when the wheel G has made one revolution a stud, i, on its face will move a wheel, G a distance equal tothe length of one of its teeth. In like manner wheclGtl will move another wheel, G

The registering-wheels are all inclosed in a case having a glass face.

The cut off valves are actuated by the attendant, who may discharge the measured grain directly into a wagon or into bags. 7

What I claim as new, and desire to secure by Letters Patent, is-

In a combined grain elevator and measurer, the cut-off valves 0 (J, loosely attached to a vibrating lever, D, fixed to a rock-shaft, E, provided with the armfand pivoted pawl g, in combination with the ratchet-wheel G of the registering mechanism, all constructed and arranged as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two Witnesses.

JAMES M. HARPER.
